Cool Activewear Brands for Kids

Posted by Tess Hansen on Jul 18th 2022

Summer is here, which means it’s time for your kids to go outside, play with friends, and soak up the sun. However, as much as you want your kids to have fun, you also want to keep them cool and comfortable, especially in the summer heat and humidity. Let’s get into the top activewear fabrics—polyester, bamboo, nylon, and spandex—before jumping into the most popular activewear for kids. With these fabrics and brands, you can let your little one run wild, without worry.


Made from plastic, polyester is like the all-you-can-eat buffet of workout wear. It’s incredibly durable, wrinkle-resistant, breathable, and lightweight, making it the fabric of choice for most parents when searching for activewear for toddlers and kids.


The bamboo pandas eat? Yep, that’s right. When processed into viscose rayon, it transforms into a soft, anti-microbial, moisture-wicking, and odor-resistant super fabric. On top of that, it’s all-natural and environmentally friendly.


Originally used for women’s stockings, nylon is a synthetic fabric that’s soft as silk, stretchy, and mold- and mildew-resistant. After your little one runs home for dinner, you don’t have to worry about that activewear growing a colony of mold in your laundry hamper.


If your little girl loves to dance or do gymnastics, spandex (also known as lycra) is the way to go. This synthetic material is breathable, dries quickly, and can stretch up to 6x its normal length—it’ll snap right back to its original shape, no problem!

In addition to these fabrics, popular kids’ activewear brands like Nike, Adidas, and Under Armour have developed their own name-brand technical materials with your comfort top of mind. Made from everything from polyester blends to titanium dioxide-infused nylon fibers, these fabrics will keep your children stay cool and comfy all summer long

Dri-FIT from Nike

Dri-FIT is a technical polyester blend designed to wick away sweat from the inside of your garment, out. This way the fabric won’t stick to your little one and they can move and play all day long. Plus, the fabric contains antibacterial agents designed to zap away odors. AKA, no more funky smells! Prices range from $25-$90 for kids’ tops and $19-$45 for kids’ shorts.

Iso-Chill from Under Armour

Under Armour is always on the forefront of innovation, and with their latest fabric, it’s no different. Iso-Chill is a revolutionary fabric that features flat, ribbon-shaped nylon fibers infused with titanium dioxide to conduct heat away from the body. With Iso-Chill boys’ Under Armour styles, you never have to worry about your little guy overheating during soccer or baseball practice. On average, an Under Armour kids’ top comes in at $40.

Climalite from Adidas

Designed specifically for warm weather, Climalite from  Adidas features an outer layer made from cotton and an inner layer made from synthetic materials. As your little one starts to sweat, this two-in-one technology pulls sweat away from the body, keeping them cool and dry. Their activewear styles run at a similar price point as Nike, with kids’ tops coming in between $20-$65 and kids’ shorts between $16-$40.
